In the second embodiment, elements having the same numeral as ones of the first embodiment have the same structures and functions, and detailed description is omitted herein for simplicity. Therotary mechanism 16 further can include agear axle 32 and arack structure 34. Thegear axle 32 pivots to thecasing 12. Thefirst connector 14 is disposed on thegear axle 32 and moves according to rotation of thegear axle 32. Therack structure 34 is engaged with thegear axle 32 and connected to thesecond connector 18. Therack structure 34 can be a board which moves at the direction parallel to the bottom of thecasing 12. - As shown in
FIG. 6 , a front edge of therack structure 34 is engaged with thegear axle 32, and meanwhile thefirst connector 14 is accommodated inside thecasing 12. As shown inFIG. 7 , thesecond connector 18 can push therack structure 34 to simultaneously revolve thegear axle 32 when theexternal plug 20 inserts into thecasing 12 and connects to thesecond connector 18. With rotation of thegear axle 32, the part of thefirst connector 14 can move out of thecasing 12, and thepower adapter 30 is switched to the used mode. A moving distance of therack structure 34 relative to thegear axle 32 can be substantially equal to a one-fourth outer diameter of thegear axle 32, which means the outer diameter of thegear axle 32 is substantially four times the moving distance of therack structure 34 relative to thegear axle 32, so that therack structure 34 can rotate thegear axle 32 at 90 degrees no matter what position therack structure 34 is engaged with thegear axle 32, and thefirst connector 14 can perpendicularly protrude from thecasing 12. - Please refer to
FIG. 8 andFIG. 9 .FIG. 8 andFIG. 9 respectively are diagrams of thepower adapter 40 in different operation modes according to a third embodiment of the present invention. Therotary mechanism 16 further can include ashaft 42 and alinkage set 44. Theshaft 42 pivots to thecasing 12, and thefirst connector 14 is disposed on theshaft 42. Two ends of the linkage set 44 are respectively connected to theshaft 42 and thesecond connector 18. The linkage set 44 can be pressed by thesecond connector 18 to rotate theshaft 42. The linkage set 44 can include afirst bar 46 and asecond bar 48. Thefirst bar 46 is disposed on a surface of theshaft 42. Thesecond bar 48 is rotatably connected between thesecond connector 18 and thefirst bar 46. For example, universal joints can be disposed on two ends of thesecond bar 48, and the universal joints can increase rotation fluency of theshaft 42 when thesecond connector 18 pushes the linkage set 44. - As shown in
FIG. 8 , thefirst bar 46 stretches from the surface of theshaft 42 and is slightly inclined toward thesecond connector 18. At the time, thesecond connector 18 is not pressed by theexternal plug 20, and thefirst connector 14 is accommodated inside thecasing 12. As shown inFIG. 9 , thesecond connector 18 moves relative to the bottom of thecasing 12 for pressing the linkage set 44 when theexternal plug 20 inserts into thecasing 12 to connect thesecond connector 18. Thesecond bar 48 of the linkage set 44 can utilize the universal joints to rotate thefirst bar 46 and theshaft 42, so as to protrude thefirst connector 14 out of thecasing 12. Thesecond bar 48 of the third embodiment not only can be the straight bar shown inFIG. 8 andFIG. 9 , but also can be the curved bar with arc structure for specific operation efficiency. Application of thesecond bar 48 is not limited to the above-mentioned embodiment, and depends on design demand. - Please refer to
FIG. 10 andFIG. 11 .FIG. 10 andFIG. 11 respectively are diagrams of thepower adapter 50 in different operation modes according to a fourth embodiment of the present invention. Therotary mechanism 16 can further include ashaft 52 and aboard 54. Theshaft 52 pivots to thecasing 12, thefirst connector 14 and theboard 54 are respectively connected to different arc positions of theshaft 52. As shown inFIG. 10 , theboard 54 is not pressed by thesecond connector 18, therotary mechanism 16 keeps the initial state and thefirst connector 14 is accommodated inside thecasing 12. - As shown in
FIG. 11 , thesecond connector 18 can move into thecasing 12 deeply by theexternal plug 20, so thatsecond connector 18 can rotate theboard 54 andshaft 52 to move the part of thefirst connector 14 out of thecasing 12. A contactingportion 56 can be selectively disposed on an outer edge of theboard 54. Thecontact portion 56 can block thesecond connector 18 to prevent thesecond connector 18 from over-slide relative to theboard 54. A planer normal vector V3 of theboard 54 can be substantially parallel to the structural direction V2 of thefirst connector 14, so as to ensure that therotary mechanism 16 can rotate thefirst connector 14 at 90 degrees to perpendicularly protrude from thecasing 12. - Please refer to
FIG. 12 andFIG. 13 .FIG. 12 is a diagram of thepower adapter 60 according to a fifth embodiment of the present invention.FIG. 13 is a diagram of thepower adapter 70 according to a sixth embodiment of the present invention. Therotary mechanism 16 can further include ashaft 62, anactuating component 64 and a guidingcomponent 66. Theshaft 62 pivots to thecasing 12. Theactuating component 64 is connected to theshaft 62 and movably disposed inside the guidingcomponent 66. - As shown in
FIG. 12 , anarc guiding slot 661 is formed on the guidingcomponent 66, and the guidingslot 661 can be the semicircle structure. An end of theactuating component 64 is located at a low end of the guidingslot 661 when thefirst connector 14 is accommodated inside thecasing 12. As thesecond connector 18 is pressed to move the guidingcomponent 66 close to theshaft 62, the end of theactuating component 64 can slide along the guidingslot 661 from the low end to the upper end, so that theshaft 62 can be revolved to move thefirst connector 14 partly out of thecasing 12. - In the sixth embodiment, elements having the same numeral as ones of the fifth embodiment have the same structures and functions, and detailed description is omitted herein for simplicity. As shown in
FIG. 13 , the guidingcomponent 66 of thepower adapter 70 can further include a guidingarc portion 663. The guidingarc portion 663 can be the semicircle sunken structure. As an end of theactuating component 64 contacts the low edge of the guidingarc portion 663, thefirst connector 14 is accommodated inside thecasing 12. When thesecond connector 18 is pressed to move the guidingcomponent 66 close to theshaft 62, the end of theactuating component 64 can slide from the low edge to the upper edge of the guidingarc portion 663. Thefirst connector 12 can rotate at 90 degrees by the rotation of theshaft 62 when the end of theactuating component 64 is located at the upper edge of the guidingarc portion 663, and the part of thefirst connector 12 can protrude from thecasing 12 to switch the power adapter from the unused mode to the used mode. - In conclusion, the power adapter of the present invention can automatically eject the first connector from the casing due to connection of the external plug. As the external plug is connected to the second connector of the power adapter, the second connector slidably disposed inside the casing can be pressed by the external plug and generate a slight movement, so as to rotate the rotary mechanism such as the above-mentioned embodiments for protruding the first connector from the casing. After the external plug is removed from the power adapter, the rotary mechanism can recover the first connector and the second connector back to the initial state by the resilient component.
- Therefore, the power adapter of the present invention has the automatically adjustable function. Comparing to the prior art, the power adapter of the present invention has advantages of simple structure, low manufacturing cost and easy operation. The power adapter of the present invention can stretch and retract the movable connector automatically according to assembly and disassembly of the external plug, and can effectively overcome the inconveniently operational drawback of the conventional adapter.
- Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
